Description Mats Lidell gentoo-dev 2023-05-01 18:15:13 UTC
app-editors/xemacs-21.5.34-r13 with use freewnn fails to compile.

The error message:
x86_64-pc-linux-gnu-gcc -c -Wall -Wno-switch -Wundef -Wsign-compare -Wno-char-subscripts -Wpacked -Wshadow -Wmissing-declarations -Wmissing-prototypes -Wstrict-prototypes -Wdeclaration-after-statement  -Wunused-parameter  -O3 -fno-strict-aliasing -march=native -O2 -pipe -no-pie  -Demacs -I. -I/var/tmp/portage/app-editors/xemacs-21.5.34-r13/work/xemacs-21.5.34/src -DHAVE_CONFIG_H -I/usr/include/freetype2 -I/usr/include/harfbuzz -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include mule-wnnfns.c
In file included from mule-wnnfns.c:273:
/usr/lib/gcc/x86_64-pc-linux-gnu/13/include-fixed/wnn/commonhd.h:54:10: fatal error: wnnerror.h: No such file or directory
   54 | #include "wnnerror.h"
      |          ^~~~~~~~~~~~
compilation terminated.

Reason is that gcc-13 installs "fixed" includes for wnn that makes commonhd.h be picked up from /usr/lib/gcc/x86_64-pc-linux-gnu/13/include-fixed/wnn/commonhd.h where wnnerror.h is not located, so wnnerror.h is not found.
